Reaction Steps

To a mixture of 1.35 g of 5-chloro-2-methyl-6-phenylpyrazolo[1,5-a]pyrimidine and 1.04 g 4-formylphenylboronic acid in 20 ml 1,2-dimethoxyethane are added 10.8 ml of a 10% w/w sodium carbonate solution and 120 mg dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium (II). The resulting mixture is heated to 100° C. by microwave irradiation under an inert gas atmosphere for 75 min. The work up is performed by diluting the reaction mixture with water and dichloromethane, separating the phases and extraction of the aqueous phase with dichloromethane. The combined organic layers are dried over sodium sulphate and evaporated. The crude product is purified by chromatography on silica gel (dichloromethane/methanol) to yield the desired product.
